Answer:
a stable octet state
Explanation:
a stable octet state is when all the energy levels of the atoms are filled with electrons and they are stabe
Answer : The molecule 
is a polar molecule.
Explanation :
Polar molecule : When the arrangement of the molecule is asymmetrical then the molecule is polar.
Non-polar molecule : When the arrangement of the molecule is symmetrical then the molecule is non-polar.
The given molecule is,
The electronegativities of oxygen and fluorine are different. The molecular geometry of is bent. As, Fluorine is more elctronegative than the oxygen. So, the arrows putting towards the more electronegative element i.e, fluorine. These arrows do not balance each other. Due to this, the asymmetrical arrangement of these bonds makes the molecule polar.
Hence, the given molecule is polar.
Answer:
A
Explanation:
I guess it's a, because nuclear decay is likely to occur when either the mass or atomic number is greater than 83.
Explanation:
biotic factors are the things which have life like animals and plants
And Abiotic factors are the things which don't have life like air,stone and river
